Detecting gas-compressor fugitive methane leaks

| By Gerald Ondrey

The ST75 Series thermal mass flowmeter (photo) provides precise CH4 gas monitoring to detect hazardous, non-compliant and costly gas leaks. The compact ST75 offers accurate, repeatable CH4 measurement to meet environmental regulations, making them suitable for crowded equipment areas where gas monitoring and measurement is essential. The flowmeters measure mass flow directly, producing flowrate and totalized-flow output signals and readouts in pounds or metric tons of emitted gases for mandated monitoring and reporting. The ST75 detects slight changes in flow, making it suitable for use in leak detection. Gas compressor stations commonly utilize dry gas seals that can be a source of fugitive methane emissions. — Fluid Components International (FCI), San Marcos, Calif.
